Product details
Overview
TLE8082ESXUMA1 from Infineon Technologies is a small engine management IC designed as a companion to TLE8080-xEM/TLE8088EM for OBDII-compliant EURO5/BHARAT VI 2-/3-wheeler EFI systems. It integrates four low-side drivers (three standard + one with O₂-heater current measurement), 6.5 V pre-regulator with external FET control, dual 5 V tracked supplies (sensor & communication), SPI interface, and window watchdog - all qualified per AEC-Q100 for automotive use.
For engineers reviewing the TLE8082ESXUMA1 datasheet, TLE8082ESXUMA1 pinout, TLE8082ESXUMA1 application, or TLE8082ESXUMA1 equivalent, this IC serves as a compact, RoHS-compliant solution for emission-critical combustion engine control in motorcycles, scooters, marine craft, and snowmobiles - with diagnostic coverage across all power stages and robust thermal/overcurrent protection.
Technical Context
The TLE8082ESXUMA1 implements a dedicated KEY input for permanent supply and after-run functionality, enabling ignition-independent post-engine operation. Its voltage monitoring includes independent tracking of V5VI (sensor supply) and COM5V (communication supply), each with undervoltage reset and overtemperature detection (T5V and COM5V channels).
SPI communication supports parallel operation with TLE8080ES for multi-IC coordination in complex engine control units. The four low-side drivers feature integrated open-load/short-to-GND diagnosis in OFF-state, priority-based fault bit assignment, and configurable watchdog states (normal, afterrun, safe, ready) with error counter and reset timer integration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Input Range | VS: 5.5 V to 28 V - supports wide battery voltage range including cold-crank conditions in 12 V automotive systems. |
| Pre-regulator Output | V6VI: 6.5 V ±0.3 V - powers sensor and communication supplies via external MOSFET controlled by VG gate driver. |
| Sensor Supply | T5V: 5.0 V ±0.1 V, tracking V5VI - provides stable, low-noise reference for engine sensors (e.g., MAP, TPS, crank position). |
| Communication Supply | COM5V: 5.0 V ±0.1 V, tracking V5VI - powers CAN/LIN transceivers or other on-board communication ICs. |
| Low-Side Drivers | 4× LS outputs: OUT1–OUT3 rated ≥1.5 A continuous, OUT4 with integrated current sense (CFB4) for O₂-heater control and diagnostics. |
| Watchdog Type | Window watchdog with programmable timeout (1.6 ms to 2.5 s) and separate afterrun mode - ensures fail-safe behavior during engine shutdown sequences. |
| Diagnostic Coverage | Per-output OFF-state diagnosis (open load/short to GND), overtemperature (T5V/COM5V), and V5VI undervoltage - reported via SPI-accessible General and Output Stage Diagnosis Registers. |

| 24 T5V | Sensor Supply Output | 5 V tracked output for engine sensors; internally monitored for overtemperature (T5V_OT) and regulation accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| Dual Tracked 5 V Supplies | T5V and COM5V independently track V5VI input with ±0.1 V tolerance - eliminates need for external LDOs while maintaining sensor/transceiver rail integrity. |
| O₂-Heater Current Sensing | Integrated current feedback on OUT4 (CFB4 pin, 10 mV/A gain) enables closed-loop heater control and real-time open-load detection without external shunt or amplifier. |
| After-Run Functionality | Dedicated KEY input triggers extended post-ignition operation (e.g., catalytic converter cooling, purge valve cycling) without requiring continuous ignition power. |
| Comprehensive OFF-State Diagnostics | All four low-side outputs support open-load and short-to-GND detection while disabled - critical for verifying harness integrity before engine start. |
| AEC-Q100 Qualified | Qualified to Grade 0 (−40 °C to +150 °C ambient) with full thermal, ESD (HBM ±2 kV), and lifetime reliability validation - suitable for under-hood motorcycle/marine environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar small engine management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE8080ES | Lacks O₂-heater current sense (CFB4), single 5 V supply (no COM5V), no KEY input or after-run support - simpler feature set, lower pin count (20-pin). | Targeted at basic EFI systems without OBDII diagnostics or dual-rail communication requirements. | Select when cost-sensitive designs omit O₂-heater closed-loop control and require only sensor supply. |
| TLE8088ES | Includes 8-channel low-side drivers, higher integration (integrated pre-regulator FET), but no CFB4 or KEY input - larger footprint (36-pin PG-TSDSO). | Designed for multi-cylinder engines (e.g., 4-stroke ATVs) needing more actuator outputs and higher current capacity. | Select when scaling beyond 4 loads is required and board space allows larger package; not drop-in compatible. |
Compared with TLE8080ES, TLE8082ESXUMA1 adds O₂-heater current feedback and dual tracked supplies essential for OBDII compliance; versus TLE8088ES, it trades channel count for enhanced diagnostics and after-run capability in a smaller 24-pin package optimized for 2-/3-wheeler space constraints.

FAQ
What is the maximum continuous current rating for the low-side drivers?
OUT1, OUT2, and OUT3 support ≥1.5 A continuous DC current at TA = 150 °C with proper PCB copper area (≥200 mm² thermal pad). OUT4 is rated for ≥1.2 A continuous with integrated current sensing. All outputs include overcurrent foldback and thermal shutdown at junction temperatures exceeding 175 °C.
How does the KEY input enable after-run functionality?
The KEY input remains active after ignition-off, allowing the IC to maintain regulated T5V and COM5V supplies and sustain selected low-side outputs (e.g., O₂-heater, purge valve) for programmable durations. This is managed by the internal state machine transitioning to Afterrun WD Ready/Safe states, independent of VS voltage decay.
Can the TLE8082ESXUMA1 operate without an external MOSFET?
No - the pre-regulator requires an external N-channel MOSFET connected between V6VI and VS, with VG driving its gate. The IC provides only the gate driver (VG), charge pump (CP), and voltage reference; omitting the MOSFET disables V6VI, T5V, and COM5V regulation entirely.
What SPI configuration is required for diagnostics readout?
Diagnosis registers (General Diagnosis, Output Stage Diagnosis, Watchdog Register) are accessed via standard SPI Mode 0 (CPOL = 0, CPHA = 0) at ≤10 MHz. Each read requires a 16-bit frame: first byte = register address (0x01–0x05), second byte = dummy (0x00); response appears on SO during second byte clocking.
